IMPULSE DISC
The balance stop mechanism is purely
mechanical.
In the running position, the tip of the
stem butts ogoinst the stop lever and
keeps the tip of the stop lever awoy
from the balance impulse disc.
In the stop position (when the stem
is pulled out into the set position),
the tip of the stop lever butts against
the impulse disc on the balance, thus
stopping the
balance.
